Murus Structural Insulated Panels (also referred to as SIPs, stress skin panels, foam core panels, or sandwich panels) are a highly energy efficient building material that is superior to 2x stud and fiberglass batt construction for exterior wall, roof, and floor applications in residential and light commercial construction.

Murus SIPs are shipped throughout North America from our manufacturing facility in Mansfield, Pennsylvania. Murus panels are comprised of a rigid foam insulating core made from Polyurethane (PUR), Expanded Polystyrene (EPS), or Extruded Polystyrene (XPS), which is bonded between sheets of structurally rated Oriented Strand Board (OSB). Murus structural insulated panels provide insulated, finish-ready exterior and interior surfaces and the composite construction of Murus panels speeds installation for faster shell-in.

Whether you choose PUR, EPS, NEOPOR EPS, or XPS, Murus SIPs offer superior insulating properties with R-values as high as 6.76 per inch of panel core thickness for optimal energy efficiency. Murus SIPs are an ideal component for most low-rise commercial and residential LEED and Green building projects. Murus SIPs are engineered to be thermally stable, maintaining their R-value over time, and can save significantly on heating and cooling energy consumption.

ENERGY STAR, energy efficiency, a healthy living environment, design flexibility, fast installation - these are just some of the rewards for building with Murus SIPs - a better way to build for a better way to live.
